Sole



FIG. 1 is a side view of a sole, showing my new design;

FIG. 2 is an opposite side view thereof;

FIG. 3 is a front view thereof; and,

FIG. 4 is a rear view thereof.

The broken lines shown in the figures that are immediately adjacent to the shaded areas and define unshaded regions represent the bounds of the claim. All other broken lines including the features within the broken line boundaries and the broken lines on the bottom surface are directed to portions of the sole. The broken lines form no part of the claimed design. 

CLAIM I claim, the ornamental design for sole, as shown and described.
